A computation model is developed, where flow dynamics together with heat and mass transfer in a turbulent two-phase gas-droplet developing tube flow are numerically studied. Turbulent characteristics of the gas phase were calculated using the Nagano-Tagawa LRN k - model. It is shown that, with increasing initial droplet diameter the heat transfer between the duct surface and the vapour-gas mixture becomes much less intense, whereas the wall friction increases only insignificantly. The computed flow-dynamics and heat and mass transfer data are compared with previously reported experimental and numerical results, and a fairly good agreement between the compared data is obtained.
